1 Claim.

This invention relates to cans of the type which have a body section and a seamless neck or coverreceiving section secured to the body section with a double lock seam and arranged to form an extension of the body section and thus add to the capacity of the can.

One of the objects of the invention is to provide a novel can of this type in which the cover fits the neck section with a friction fit and which is constructed to facilitate the removal of the neck section.

In order to give an understandingof the invention I have illustrated in the drawing a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claim.

Fig. l is a partial sectional view of a can embodying my invention;

Fig. 2 is a similar view of a can showing a different embodiment of the invention;

Referring first to Fig. 1 the can is formed with the body section I and the neck section 2. The body section I is made with the usual side seam 3. The neck section 2 is a seamless section and is made by being pressed into shape from a suitable blank. These two sections are locked together by a double lock seam 4 which extends around the exterior of the can and the neck section 2 projects above the body section I and adds to the capacity of the can.

The neck section 2 is so constructed that its lower end sets within the upper end of the body section I and as herein shown the lower end of the neck section 2 is bent back on itself as indicated at 5 to form a lower edge of double thickness and this lower edge of double thickness nests or sets into the upper end 6 of the body I- p The neck section and the body section I are formed in the first place with outwardly-extending seaming flanges 8 and 9 as shown by dotted lines in Fig. 1, which flanges mate and contact with each other when the neck section is assembled with the body section. These flanges are afterwards rolled together to form the double lock seam 4.

The body section I is shown as having a portion III of reduced diameter directly below the neck section, said portion III having the same interior diameter as that of the neck section.

II indicates a cover or closure for closing the open end of the can and in the construction shown in Fig. 1 this cover is in the form of a plug cover which has a tight frictional fit within the upper end 12 of the neck section. The cover is shown as formed with the annular groove I3 which provides the two spaced cylindrical walls I9 and I5 that are connected by the portion ll.

The outer wall I5 is that which flts frictlonally within the upper end I2 of the neck portion.

The upper end of the outer wall Ii is preferably rolled over. to provide the bead I1 and the upper end I2 of the neck portion is also rolled over to provide the bead l8.

The neck portion 2 is made with a stop portion designed to limit the extent to which the plug 10 cover I I can be forced into the neck 2. This stop portion may conveniently be formed by deforming the neck 2 so as to provide an interior shoulder at one or more points thereon. As shown in the drawing the neck portion is deformed by pro- 15 viding it with an interior rib '29 which may be a continuous rib extending entirely around the neck or may be one or more short ribs spaced about the neck.

The construction is such that when the cover is forced into the neck as far as the stop shoulder will permit the bead II on the cover is spaced from the bead I8 on the neck as indicated at 2!, this space being sufllcient to receive a tool or implement, such as a screw driver or the like, by 2 which the cover can be pried oil from the neck.

In Fig. 2 I have shown a different embodiment of the invention wherein the cover is provided with an exterior skirt portion which frictionally engages the exterior of the neck. In this embodiment the can body section I has the same construction as that shown in Fig. 1 and the neck portion 2a is similar to the neck portion 2 in Fig. 1 with the exception of the stop portion. In other words, the neck portion 2a of Fig. 2 is formed with the two-ply lower end 5, which sets into the upper portion 6 of the body section I and the neck and body sections are locked together by the double lock seam l.

In the construction shown in Fig. 2 the upper edge of the neck section 20 is bent inwardly to form an interior bead 23 which constitutes the stop portion that determines the position of the cover when it is in operative position closing the can.

The cover in Fig. 2 is indicated at 2| and it is formed with the cylindrical wall 22 which frictionally fits within the head 23 at the top of the neck portion and it is also formed with the depending skirt portion 24 which frictionally engages the exterior of the neck. The length of the skirt portion is such that when the cover has been placed on the can to close the latter and the curved portion 25 of the cover which joins the skirt 24 and the wall 22 is in engagement with the stop portion or bead 23 ot the neck, the lower edge of the skirt will be spaced slightly from the double lock seam I as indicated at 26, this space 26 being suflicient to receive a tool or implement for prying the cover 011 from the can.

The skirt 24 is shown as having a bead 21 at its lower edge which gives the skirt of the cover a sufilciently wide lower edge so as to give a sumcient bearing for said tool or implement. If an implement such as a screw driver is used the cover may be pried off by inserting the screw driver in the space 28 and then twisting the screw driver to force the cover upwardly.

'I claim:

A can having a body section and a seamless neck section secured to the body section with a double lock seam, said neck section forming an extension of the body section and the upper edge of the neck section being curved outwardly to present a bead, the lower end oi the neck section being bent back on itself with the two plies in contact with each other and the two-ply portion of said section fitting within the upper end of the body section, and the body section having an interior shoulder engaging the lower end of the neck section, a cover having a frictional fit within the neck section and having a bead at its periphery, said neck section having an internal shoulder forming a stop portion against which the cover rests when it is in operative position closing the can, said stop portion being so positioned that when the cover rests against it the head of the cover is spaced slightly from the bead of the neck, thereby providing a space in which an implement may be inserted for prying the cover from the can.
